Two years ago this month, Adam Yauch - who helped found the groundbreaking rap act The Beastie Boys -- lost his fight against cancer. Yauch, also known by his stage name "MCA," was more than a musician, however. A devout Buddhist and peace activist, Yauch was a prominent advocate for Tibetan independence. Earlier this month, on MCA Day, a group of Buddhist monks performed a mind-blowing, and totally fitting, tribute to the beloved musician.
